Pre-storage preparation: Select a clean, leeward, moisture-proof, and warm place indoors, such as near the corner of the stove. First level the site, block the gap around the wall, and use earth blocks to build a soil enclosure more than one meter high. The size of the fence depends on the amount of storage. Generally, for every 100 kilograms of sweet potatoes, 150 kilograms of rice hulls are used. At the same time, prepare several mats or straw mats made of straw.
In the operation and management, we must grasp the following points: 1 strict selection of potatoes, requiring storage and preservation of the tangerine should be no cracks and cuts and digging, disease-free spotted wormholes, no outcrops and water-like spots. 2 After the potato block is selected, first disperse lime in the bottom and around the soil surrounding the soil, then lay 35 cm thick dry rice hulls and a layer of straw mat around. 3 When placing sweet potatoes, gently handle them, and maintain a certain gap between them, and do not touch each other. Put a layer of sweet potatoes to cover the first layer of the husks, so as not to see the potato as the standard. The straw mat and the outer wall are filled with rice husks to prevent air leakage. The potato dumplings are generally about 1.5 meters thick. The top layer covers more than 35 centimeters of the husk and is covered with a straw mat. 4 During storage, attention should be paid to the “four preventionsâ€, that is, waterproof, moisture-proof, anti-freeze, rodent-proof and other work. 5 Take the potatoes from top to bottom during storage. Always use chaff to fill in the potatoes and add straw mats.
